Scaling California’s most innovative ecommerce brands.
Expert Shopify Plus development and ecommerce design for California lifestyle, tech, and apparel brands. Build a store that scales.
What does an ecommerce development agency build?
An ecommerce development agency builds the engineering layer of an online store: custom storefronts, platform integrations, and the applications that connect commerce to the rest of a business. On Shopify that covers theme and Liquid development, custom apps against the Admin and Storefront APIs, headless builds using Hydrogen or a separate framework, and data synchronisation with ERP, OMS, and PIM systems. The decision that shapes an engagement most is architectural: a themed Shopify storefront and a headless build have very different cost, performance, and maintenance profiles, and that choice is usually made before any code is written.
Innovation demands cutting-edge infrastructure.
California brands move fast. If your development team is slow, or your current platform can’t handle headless architecture, bespoke app requirements, or sudden viral traffic spikes, you will lose momentum.
Modern tech stacks for explosive growth.
We act as an extension of your team, providing senior-level technical direction and flawless execution. We build flexible, headless, or highly customized Liquid architectures that scale infinitely.

How we work with California brands
- Establish what is already working: Before recommending changes we crawl the store and review Search Console and analytics to identify which pages earn impressions and links, and which titles and headings are attached to rankings worth protecting.
- Find the funnel loss, by device: We segment conversion by device and browser and review session recordings. An acceptable aggregate conversion rate frequently hides a mobile figure that is half the desktop number, which changes where the work belongs.
- Build against platform constraints: Catalogue structure, variant modelling and checkout are fixed points on Shopify. Templates ship with product data, canonicals and structured data present in the server-rendered HTML, verified with a crawler that executes no JavaScript.
- Release, measure, iterate: URLs stay stable unless there is a reason beyond aesthetics to change them. Coverage and logs are monitored after each release, because missed redirects appear as 404s well before they appear as lost rankings.
California Ecommerce Experts FAQs
Do you work with brands outside the Bay Area and Los Angeles?
Yes. The work is remote by default and we work with brands across California and the wider United States. The California focus reflects where a large share of the DTC and Shopify Plus brands that reach us are based, not a restriction on who we take on.
What does CCPA compliance require from a Shopify store?
This is a legal question for your counsel rather than an engineering one, but the store-side implications are practical: a working mechanism for customers to request access to and deletion of their data, honest disclosure of what third-party scripts collect, and consent handling that actually gates those scripts rather than merely displaying a banner. We build the technical side so your policy is enforceable; the policy itself is yours.
Can you work with our existing theme rather than rebuilding?
Usually yes, and it is often the better answer. If the theme is well built and the problem is specific — performance, a broken mobile flow, missing structured data, thin rendered HTML — then targeted work is faster, cheaper and carries far less risk than a rebuild that puts what currently works back on the table.
Do you handle headless builds?
Yes, and we also talk brands out of them. Headless is justified by content complexity, multi-market requirements or multi-surface delivery — not by a slow storefront, which is usually caused by apps and theme code that headless does not remove. We check which case you are in before scoping.
How quickly can you start?
A diagnostic engagement can usually begin within a couple of weeks, and it is how we prefer to start. It produces a ranked list of work with evidence behind it, which makes the larger scope a decision based on findings rather than on a proposal written before anyone looked at the store.
